## Deployment
|
||||
|
||||
### Step 1: Add Prisma Model
|
||||
|
||||
The `ChartOfAccount` model has been added to the Prisma schema.
|
||||
|
||||
### Step 2: Run Migration
|
||||
|
||||
```bash
|
||||
cd dbis_core
|
||||
npx prisma migrate dev --name add_chart_of_accounts
|
||||
```
|
||||
|
||||
Or manually run the SQL migration:
|
||||
```bash
|
||||
psql -d dbis_core -f prisma/migrations/add_chart_of_accounts.sql
|
||||
```
|
||||
|
||||
### Step 3: Initialize Chart of Accounts
|
||||
|
||||
```typescript
|
||||
import { chartOfAccountsService } from '@/core/accounting/chart-of-accounts.service';
|
||||
|
||||
// Initialize standard accounts
|
||||
await chartOfAccountsService.initializeChartOfAccounts();
|
||||
```
|
||||
|
||||
Or via API:
|
||||
```bash
|
||||
POST /api/accounting/chart-of-accounts/initialize
|
||||
```
|
||||
|
||||
### Step 4: Verify
|
||||
|
||||
```typescript
|
||||
// Get all accounts
|
||||
const accounts = await chartOfAccountsService.getChartOfAccounts();
|
||||
|
||||
// Get by category
|
||||
const assets = await chartOfAccountsService.getAccountsByCategory(AccountCategory.ASSET);
|
||||
|
||||
// Get hierarchy
|
||||
const assetHierarchy = await chartOfAccountsService.getAccountHierarchy('1000');
|
||||
```
